Sample Programs
There are sample programs provided with the card in C, Pascal, QuickBASIC, and several
Windows languages. DOS samples are located in the DOS directory and Windows samples are
located in the WIN32 directory.
Windows Programming
The card installs into Windows as COM ports. Thus the Windows standard API functions can be
used. In particular:
►
CreateFile() and CloseHandle() for opening and closing a port.
►
SetupComm(), SetCommTimeouts(), GetCommState(), and
SetCommState() to set and change a port’s settings.
►
ReadFile() and WriteFile() for accessing a port.
See the documentation for your chosen language for details.
Under DOS, the process is identical to programming any 16550- or 16750-compatible UART.
